I have two ics files attached to this post. One that works in Outlook 2003 that was created in Outlook 2003. The other one is created using a sql server stored procedure and the format is the same, but it will not open in Outlook 2003. How can I get this to work? I need this to be automated because I am dynamically pulling dates into the ics file and emailing the file out with the stored procedure. I've tested the files on multiple machines that have Outlook 2003, so it's not just one machine that is having a problem. The files work fine on Outlook 2007.
